- Properties
Pat-Add SU 420 shows both strong performances in reduction of static as well as dynamic surface tension. The product exhibits wetting performance in various applications. In waterborne coatings and inks Pat-Add SU 420 is used as pigment wetting and dispersing agent. Pat-Add SU 420 acts as a defoaming agent. Moreover, it contributes to improved substrate wetting properties of the coating or ink film, onto low surface tension substrates, such as plastics
- Benefits
- Easy workability. Used instead of the Pat-Add SU 4 series, in case of requiring solvent-free liquid
- Excellent pigment wetting properties
- Unlike conventional wetting agents it does not contributes to foam formation
- Strong reduction of surface tension of aquous systems
- Lower water solubility as compared to Pat-Add SU 440
- Main application areas are polymer emuslions, emuslion polymerisation,WB paints and inks
- Aids flow and leveling
Applications & Uses
- Markets
- Use Level
- 0.1% - 0.5%
- Application
Nonionic surface active agent, excellent wetting and dispersing properties in aqueous systems and a foam destabiliser. Lower water solubility as compared to Pat-Add SU 225. Substrate and Pigment wetting, Easily dispersible in water.
- Dosage & Addition
The optimal amount of PAT-ADD SU 420 to be used is system and application related, but are in case of being used as a wetting agent in the range between 0.1% - 0,5% Pat-Add SU 420 by weight of the total formula. Best incorporated under efficient mixing conditions, such as provided by high speed mixers. The optimum concentration to be used depends on the individual requirements and conditions and is advised to be determined experimentally.
